Here are the members
of the UCSB BaBar group.
If you want to find other members of the BaBar collaboration, you can
search the BaBar and PEPII database.
Our group is primarly involved with the Silicon
Vertex Detector and the DIRC
Particle Identification Detector.
Silicon Vertex Detector
Test Beam Module
Here is information about the Layer
2 module that has been assembled for the May '97 test beam at CERN.
There are a number of pictures of the assembly sequence and a spreadsheet
of the bonding map, faults, noise and gains of every strip. (April 1997)
Test Beam Analysis
Information on the testbeam analysis can be found here. (October 1997)
Prodution Wirebonding and Testing
This page shows information relating the DFA
Production. (Status, summaries, bonding maps and documentation)
Status of gluing, bonding/testing, and assembly of first six
sextants and modules
